[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-7 The present invention provides a technical solution: a cutting device for plastic products after vacuum forming, comprising a workbench 1 with a bracket 2 installed at the bottom, the workbench 1 is used to place plastic products, and is convenient for cutting the plastic products. A positioning component is arranged above the workbench 1, and the positioning component is used to position the plastic products stacked above the workbench 1, so as to avoid that some plastic products are moved by the cutting force during the cutting process, reduce the cutting error or even damage and scrapping, and the height of the positioning component is adjustable, and the positioning height of the positioning component can be adjusted according to the stacking height of the plastic products, which is suitable for cutting plastic products with different stacking heights. A mounting frame 7 is slidably arranged above the workbench 1, and a moving frame is slidably installed on the side of the mounting frame 7. The movable frame 13 is provided with a lifting assembly on the side of the movable frame 13, and a cutting assembly is installed at the telescopic end of the lifting assembly. The movement of the cutting assembly is controlled by the lifting assembly, so that the plastic product can be cut by the cutting assembly. During the cutting process, the position of the cutting assembly can be adjusted by adjusting the position of the mounting frame 7 and the movable frame 13, so that the excess material at different positions of the plastic product can be cut by the cutting assembly. It is suitable for cutting plastic products of different specifications. Cleaning assemblies are provided on both sides of the cutting assembly on the upper side of the workbench 1. The cleaning assemblies are used to clean the waste and debris generated during the cutting process to prevent the debris or waste from being adsorbed on the outside of the plastic product by static electricity and affecting the preparation quality of the plastic product.

The positioning plate 3 is moved up and down according to the stacking height of the plastic products. During the movement of the positioning plate 3, the positioning rod 4 moves in the sliding hole on the side of the workbench 1 to limit the positioning plate 3 and guide it. Thereafter, the positioning nut 5 can be adjusted to limit the movement of the positioning rod 4, so that the positioning plate 3 is pressed against the stacked plastic products to position the stacked plastic products, thereby avoiding the movement of the plastic products due to the cutting force during the cutting process, reducing the cutting error or even damage and scrapping.

[0022] A positioning spring 6 is sleeved on the outside of the positioning rod 4, and the positioning spring 6 is located between the workbench 1 and the positioning nut 5. When an upward force is applied to the positioning plate 3, the positioning spring 6 is squeezed and deformed to provide a certain moving space for the positioning plate 3, which is convenient for taking and placing the plastic products on the workbench 1. After the positioning plate 3 is not subjected to external force, the positioning spring 6 is elastically restored to its deformation and drives the positioning plate 3 to move downward, so that the positioning plate 3 can effectively position the plastic products. In addition, when the positioning rod 4 is positioned by the positioning nut 5, the positioning spring 6 can play a buffering role to prevent the positioning plate 3 from applying excessive pressure on the plastic product and causing deformation of the plastic product.
